How are changed bookmarks displayed
Changed Bookmarks are displayed in red and bold. They can optionally be sorted automatically to the top of the Bookmark list. When you open a changed Bookmark, its status is set to "read". The Bookmark is then displayed in black using the normal font style.
Folders that contain changed Bookmarks are also displayed in red and bold. The number of changed Bookmarks is shown in parentheses after the folder name.
